Maybe this is uncommon, but some of my glass discs have a mix - the center area substrate is metal, and the recordable area substrate is glass.
The light test works fine on them!

Or you can also look at the center hole, if the substrate appears to be
metal, that's a clue. Glass and metal look very different.

If one of them was recorded in the 30s, there's little chance that it'll
be glass based unless it's a dub made between 1941 and 1946. Still best
to handle these with the greatest of care, but you can easily identify a
glass disc by holding it up to the light. If no light passes through,
even faintly, you have aluminum based discs (or steel or cardboard).

Hi to all,
I don't usually post to the forum, however I read it daily and enjoy
it. I have 3 Records made on Glass that were my Aunts. 2 records,
recorded in the 40's are of the Stewart Sisters (backup group for Rudy
Vallee, she was Jean) and one is a recording, done in the 30's of her
group, "The Girlfriends Trio". I was hoping someone could direct me
to a good internet site or book to educate myself about these records.
Also, I am sure there is a special way to store them, right now I have
them in a large, 78rpm Album in a verticle position. Any thoughts?
Thanks so much,
Jackie
